Abstract
When an air-conditioning is started, a determination is made as to whether a power relay is run so as to keep a compressor in a power-on state. When the power relay is in the power-on state, the running current of the power relay is detected. At this point, if the current value does not reach to a predetermined value, it is determined that the compressor is stopped in an exterior unit for protection.
